PASTING MECHANISM FOR CIGAR AND CHEROOT MACHINES.

Specification of Letters Patent.

Patented Jan. 8, 1918.

Application filed July 23, 1917. Serial No. 182,285.

To all whom it may concern:

Be it known that I, JOHN E. Non UEs'r, a citizen of the United States, and residing at Richmond, in the county of Henrico and State of Virginia, have invented new and useful Improvements in Pasting Mechanism for Cigar and Cheroot Machines, of which the following is -a specification.

This invention relates to certain novel and useful improvements in a pasting mechanism adapted particularly for applying paste to a leaf carried by the leaf carrier of cigar and cheroot making machines.

In the present instance, it is my purpose to provide a pasting mechanism through the agency of which the paste may be uniformly and evenly applied to the leaf at certain predetermined times in the travel of the carrier.

In machines for making cigars and cheroots, a pasting mechanism is employed which is adapted to supply a dab of paste to a wrapper leaf on the leaf carrier.

The usual type of pasting mechanism is of complicated structure, being composed of a relatively large number of parts and operated from a grooved cam wheel driven from the power mechanism of the machine.

Furthermore, under varying conditions of use, it is a ditlicult and tedious operation to adjust the various parts of the ordinary pasting mechanism in order to insure that the latter will properly supply the paste to the wrapper leaf at the proper moments in the travel of the leaf carrier, and the result is that frequently, through mal-adjustment of the parts, there results not only an improper application of the paste, but also a wasting of the latter. Another disadvantage incident to the ordinary type of pasting mechanism is that when, for any reason, one pasting mechanism must be discarded and another substituted, it is necessary to supply a new grooved cam wheel for the train of operating mechanism, thereby involving considerable expense and delay, for the grooved track of such cam wheel must be cut with the greatest nicety to insure the proper operation at predetermined moments.

In the present instance, Ihave provided a pasting mechanism wherein the above mentioned disadvantages are cbviated, for I dispense entirely with the grooved cam for operating the mechanism, and also so construct the other parts of the latter that thepaste will be uniformly and evenly distributed continuously and at the proper time.

Furthermore, it is my purpose to provide a pasting mechanism wherein the various parts may be readily and instantly adjusted to accommodate such mechanism to varying conditions under which the machine is to be operated, thus insuring that such pasting mechanism will be brought into action at precisely the proper moment to supply paste to the wrapper leaf on the leaf carrier.

It is also my purpose to provide a pasting mechanism which will embody the desired features of simplicity, etliciency, and reliability: which will so operate as to accomplish a saving of paste while in operation; which may be adjusted to any selected position; and which will cooperate with other coacting parts of the machine in proper timed relation.

\Vith the above recited objects and others of a similar nature-in view, my invention consists in the construction, combination, and arrangement of parts set forth in and falling within the scope of the appended claims.

In the accompanying drawings:

Figure 1 is a view in side elevation of a pasting mechanism embodying my invention, such view also illustrating the leaf carrier conventionally in dotted lines, and showing so much of the power mechanism as is necessary to understand the operation of my mechanism.

Fig. 2 is a top plan view of the mechanism shown in Fig. 1.

Fig. 3 is a perspective view of the pasteapplying arm. and a portion of the operating devices thereof.

Fig. 4 is a detail sectional view of the connection between the crank arm and the link rod for actuating the pasting mechanism proper.

Referring to the accompanying drawings in detail, the letter A indicates conventionally a portion of the side frame of the machine, while the well-known leaf carrier, which carries the wrapper leaf intended to receive the paste is conventionally shown in dotted lines at B. Thepasting mechanism is indicated as an entirety by the letter C, and is of course intended to supply paste to the tip end of a wrapper leaf on the leaf carrier 13 when the latter is positioned theremy pasting mechanism includes a bracket 1 fastened to the slde frame of the machine and supporting the upwardly extending slightly bowed standard 2, the latter being formed with a longitudinal web 3, the upper end of which is formed with a Y-shaped section 4, the arm 5 of which terminates in a bearing sleeve 6, while the other arm 7 terminates in the bearing sleeve 8. Mounted to turn Within the sleeve G is a second sleeve 9 through which extends the rod 10, a setscrew 11 being employed to adjustably secure the rod 10 within the sleeve 9 and thus permit said rod to be shifted longitudinally of the sleeve and then fastened in a selected position, Carried by this rod 10 is a block 11 bored as at 12 for the reception and passage of the paste-applying arm 13, a setscrew 14 being employed for adjusting the arm 13 in the block 11 and thus lengthen? ing or 'shortenin the throw of the pasteapplying arm. he block 11" is also intended to be adjusted lengthwise of its sup porting rod 10 and may be either friction-- ally held on the latter or positively fastened as by the set-screw 15. The numeral 16 indicates a cam bar, one end of which terminates in a collar 1-7 adapted to fit over the outer end of the rod 10 and to be fastened thereto inanv suitable manner as by a pin or screw 18. This cam bar 16 is preferably formed of a piece of metalwh-ich is T-shaped' in cross-section, as shown in Fig. '3, and adjacent the end 17 is formed with a V-shaped bend '19 constituting the operating or toe section of the cam bar. 'Tli'ersleeve 8 of the standard has "socketed "therein a stop pin 20 which projects above this toe section of the cam bar and acts to limit the upward swing ing movement of such cam bar as will -be readily understood.

In order .to rock-the cam bar up andtdown, and thus elevate and depress the ,paste-ap ,plying arm 1?. I employ a lever '21,"the free end of which is provided with a roller 22 adapted toride against the under side of the cam bar, as shown in Fig. 1. T his jlex'er'2l is pivoted to rock upon the 'shaft'23 projecting from the standard 2 and the lower end of this lever'is bent'a't an angle to the main portion thereof, as shownatfl24, 'In order to rock the lever21, I fasten a small crank arm "25 to the shaft 26 of'the machine, which may be'the power shaft of'the latter, or may be'a separate shaft driven "from the ,power shaft, and to the, outer end of this crank a m-25 the e s p oted as at 26".a short s ing ng s1eev 27in which is adjustably .threadednneentl. 'f thereonaeetingrotlfgg,

- lowering the the opposite end of this rod being threaded in the sleeve 29 pivoted at 80 to the lower end of the angular section 2 1 of the lever 21. The numeral 31 indicates a paste pot or receptacle of any suitable construction, and which is fastened to the standard 2 so'as to lie directly beneath the rocking paste arm 13, the free end of the latter being in the nature of a flattened coil 13 which is adapted to be dipped into the paste in the receptacle 31 on downward movement of the arm,'and on the upward movement of the latter, is adapted to contact with the tip end of a wrapper leaf on the leaf carrier B, and to transfer.

paste to the leaf. The upper face of this coil terminal 131which contacts with the leaf is preferably flat,as indicated in Fig. 3, so as to uniformly and evenly apply the paste. By reference to Fig. 2, it will be seen that one side, or the outer side,'of the paste pot or receptacle is formed with relatively flat or vertical wall, this'being for the purpose of permitting the close mounting and adjustment of the operating mechanism for the paste-applying arm. 7

From the above description. taken in connection with the accompanying drawings, the construction and operation of my improved pasting mechanism will be readily apparent. In the rotation of the shaft 26, when the machine is running, motion will be transmitted to the crank arm 25 and conapplying arm 13 out of and dipping it into the body of paste in the paste pot. In Fig. 1, it will 'beseen that the roller 22 is just about at the depression or toe of the cam bar and at this time, the latter is almost in its highest position of elevation, and consequently the pasteapplying coil '13 at the end of the arm 13 is in position to apply paste to a leaf carried by the leaf carrier 13 which latter has been brought to position directly over the mechanism.

As the roller 22 of the lever .21 leaves the toe end moving outwardly 'to the left, the cam bar '16, being unsupported by the roller, will drop down, thus gradually paste arm 'into the receptacle 31, this taking place .without splashing the paste or causing the formation of bubbles, as commonlyoccurs with the usual pasting mechanism employed in machines of this class. On the return or forward strokeof paste arm "by its actuating thelever'21,.the roller 22 will strike the toe end ill?!" at pastezapplying .arm to he .13. n

brought into contact with and to apply a dab of paste to the tip end of the wrapper leaf carried by the carrier B. After passing the toe of the cam bar 16, the roller 22 will move into contact with the straight section of the bar 16, first forward or toward the free end thereof and then backward or again toward the toe thereof, and this reciprocation of the roller 22 against the straight section of this cam bar 16, due to the swinging movement of the lever 21, will cause the paste arm to drop away or be lowered relative to the leaf carrier, but will not permit it to enter the receptacle. This movement of the paste carrying arm which might be termed a dwell will take place in order to allow the leaf carrier to move away from the paste applying mechanism'before the lever 21 returns on its backward stroke and contacts with the toe of the cam bar because paste is only applied to the wrapper on the leaf carrier but once in each cycle of operation, or on the forward stroke of the lever 21, or its movement toward the right of Fig. 1. At the time the roller 22 contacts with the toe of the cam bar 16 on the rearward movement of the lever 21, or its movement toward the left in Fig. 1, the leaf carrier is not in position directly over the paste-applying arm, but has been moved away from the same and is in position at or ad aCent to the wrapping mechanism of the machine. In other words, the lowering and dwelling movement imparted to the paste applying arm 13, as above described, allows of the lapse of sufiicient time for the leaf carrier to move away from the pasting mechanism before the paste applying arm of the latter can again be elevated.

By this cycleof operation, I insure that the arm will be brought in contact'or will move in proper timed relation to apply the paste to the leaf carrier. It will further be seen that I practically attain a universal adjustment of the paste-applying arm by the construction herewith shown, so that such arm may be shifted or adjusted to accommodate the particular machine on which it is to be used, or to compensate for such variations as may be made in the adjustment of the machine or the leaf carrier. It will also be seen that should it he necessary to change the driving mechanism of my pasting mechanism, there will be no grooved cam wheel to change or substitute on the shaft 26, as is commonly the case, as I have dispensed entirely with such grooved wheel and the cam roller commonly working therewith, employing in place thereof, the simple arrangement of crank arm and connecting rod herein shown.

lVhile I have shown and described one preferred embodiment of my invention, I wish it to .be understood that I do not confine myself to all the precise details of construction herein set forth by way of illustration, as modification and variation may be made without departing from the spirit of the invention or exceeding the scope of the appended claims.
